A Three-Dimensional Tetraphenylíethene-Based Metal-Organic Framework for Selective Gas Separation and Luminescence Sensing of Metal Ions.

A three-dimensional porous metal-organic framework (MOF), UTSA-86, made up of cadmium ions and a chromophoric tetraphenylethene-based tetracarboxylate ligand, 4′,4′′′,4′′′′′,4′′′′′′′-(ethene-1,1,2,2-tetrayl)tetrakis(1,1′-biphenyl-4-carboxylic acid (H₄ettc), has been synthesized and characterized by single-crystal X-ray diffraction analysis. This multifunctional MOF exhibits permanent porosity, selective gas uptake, and luminescence sensing of metal ions. [ABSTRACT FROM AUTHOR]
